The adoptive parents of a 13-year-old North Carolina girl who was tortured before she was killed in 2011 have been charged with first-degree murder, authorities said Tuesday.

Casey and Sandy Parsons, already in prison for tax fraud, were indicted by a grand jury on Monday in the slaying of their teen daughter, Erica Parsons.

Erica’s body was found in September of 2016 in South Carolina, five years after she vanished. Already in prison, adoptive dad Sandy Parsons had shown investigators where he buried the child shortly before Christmas in 2011.

The teen had lived with her adoptive parents in Rowan County from 2000 until the time of her disappearance.

The couple have been charged with first-degree murder, child abuse, concealment of death and obstruction of justice, according to WBTV.

Experts say the suspects repeatedly inflicted “child torture” on the child, according to the Charlotte Observer.

Erica was not even reported missing until 2013, and the couple went on “Dr. Phil” McGraw’s national TV show to plead for help in finding their adoptive daughter.

Sandy Parsons admitted he locked Erica in a closet, beat her “with belt buckle” and bent her fingers back and choked her, according to the Observer.

Both continued to collect benefits and were convicted of tax fraud in 2014.
